DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1, 4 to 6, 8, and 9, the preferred embodiment of a stroller assembly according to this invention includes a car seat 1 and a stroller 2 for supporting the car seat 1. The car seat 1 includes a seat body 11 and an engaging member disposed on the seat body 11. The stroller 2 includes a frame 3 and a stroller seat 4. The frame 3 includes a front leg frame 31, a rear leg frame 32, a back frame 33, two armrests 34, a pair of front wheels 35, and a pair of rear wheels 36. The front leg frame 31 is generally U-shaped, and includes a front leg rail 311 and two front legs 312 connected respectively to two ends of the front leg rail 311. The front wheels 35 are disposed respectively on bottom ends of the front legs 312. The rear leg frame 32 includes two rear legs 321 connected respectively and pivotally to top ends of the front legs 312. The rear wheels 36 are disposed respectively on bottom ends of the rear legs 321. The back frame 33 is in an inverted U-shape, and has two bottom ends connected respectively and pivotally to two rear leg connecting rods 331 that are connected respectively and pivotally to the rear legs 321 at bottom ends thereof. The armrests 34 have front ends connected respectively and pivotally to top ends of the rear legs 321, and rear ends connected respectively and pivotally to two sides of the back frame 33. The rear armrests 38 have front ends connected respectively and pivotally to the armrests 34, and rear ends connected respectively and pivotally to the rear leg connecting rods 331 of the frame 3.

The stroller seat 4 is disposed in a space defined by the front and the rear legs 312, 321 as well as the back frame 33. The stroller seat 4 is connected pivotally to a pair of opposite connecting rods 37 having front ends connected respectively to the front legs 312 of the front leg frames 31, and rear ends connected respectively to the rear leg connecting rods 331 of the back frame 33. By this arrangement, the stroller seat 4 is pivotable between an upright position whereat the stroller seat 4 is substantially vertical and connectable to the car seat 1, and a horizontal position whereat the stroller seat 4 is substantially horizontal and the baby can sit thereon.

As can be more clearly seen from FIGS. 2 and 3, the stroller seat 4 is pivotally mounted on the pivot mountings 41, 371, and consists an inverted U-shape support frame 43 pivotally mounted on the undersurface of the stroller seat 4. The support frame 43 comprises an upper horizontal rod 432 interconnecting two vertical rods 431 which have their lower ends pivotally engaged in respective retaining blocks 44. By such arrangement, the support frame 43 may be pulled out to extend beyond the stroller seat 4. The upper horizontal rod 432 provides a support position for the front retaining portion 12 of the car seat 1.

An adjusting shaft 372 extends transversely on the undersurface of the stroller seat 4, and is designed to reciprocally move between locking and unlocking positions. The adjusting shaft 372 consists an inverted U-shape portion at substantially the intermediate portion thereof.

The stroller seat 4 has a segment 42 provided at the undersurface. The segment 42 comprises a first retaining groove 421 and a second retaining groove 422 along the periphery thereof. The first and second retaining grooves 421 and 422 are configured to receive a portion of the adjusting shaft 372 therein, as will be explained hereinafter.

FIG. 2 illustrates the adjusting shaft 372 disposed at a locking position whereat a portion of the adjusting shaft 372 is engaged in the first retaining groove 421. In this position, the stroller seat 4 is locked and the baby can sit upright thereon. When the handle 373 is pulled to the right as shown by the arrow direction, the adjusting shaft 372 moves towards the right direction, and that portion of the adjusting shaft 372 is disengaged from the first retaining groove 421 to dispose the adjusting shaft 372 in an unlocking position. The stroller seat 4 is thus unlocked and may pivot relative to the adjusting shaft 372. When the stroller seat 4 is pivoted to the upright position, the segment 42 attached to the stroller seat 4 is moved to bring the second retaining groove 422 thereof in alignment with the adjusting shaft 372. As the handle 373 is moved to the left, a portion of the adjusting shaft 372 is engaged in this second retaining groove 422, thereby securing the stroller seat 4 in its upright position.

FIGS. 1 and 5 illustrate the condition in which the stroller seat 4 stands upright in its upright position. In this condition, the support frame 43 is telescopically extended beyond and risen above the stroller seat 4, or is pivoted out of and risen above the stroller seat 4, so that the upper horizontal rod 432 of the support frame 43 may provide a support position for the front retaining portions 12 of the car seat 1, while each of the rear retaining portion 13 of the car seat 1 is supported by respective upper portion of the rear armrest 38. In this manner, the car seat 1 is securely supported.

FIG. 4 is a side view to illustrate the stroller seat 4 of the stroller 2 according to the present invention in its seated (horizontal) position and the baby can sit upright thereon. In this horizontal position, the stroller seat 4 is substantially horizontal and the support frame 43 is located lower than the stroller seat 4, so that the baby can sit upright on the stroller seat 4.

A further embodiment according to the present invention is shown in FIGS. 6 to 9. In the drawings, like numerals indicate like elements, and the descriptions of some elements that are identical to those of the first embodiment shall be omitted.

Referring to FIG. 6, the second preferred embodiment of the present invention is different from the first preferred embodiment in that the support frame is not attached to the stroller seat, but rather is attached to a backrest 27.

In this preferred embodiment, stroller 2 likewise comprises a frame 3 and a stroller seat 4′. The stroller seat 4′ is disposed in a space defined by the front and the rear legs 312, 321 as well as the back frame 33.

FIG. 7 is a perspective view to illustrate in detail the structure of the second embodiment according to this invention that may securely support the car seat. The stroller seat 4′ is supported by a pair of opposite connecting rods 393 having front ends connected respectively to an first actuation device 50. A backrest 27 is pivoted to the first actuation device 50 so that it is pivotable relative to the connecting rods 393. The backrest 27 is in an inverted U-shape, and comprises an upper horizontal rod 272 interconnecting two vertical rods 271 which have their lower ends pivoted respectively to the first actuation devices 50.

A support frame 45 is pivotally connected to the backrest 27. The support frame 45 is substantially in an inverted U-shape, and comprises an upper horizontal rod 454 interconnecting two vertical rods 452. The vertical rods 452 of the support frame 45 have their lower ends pivoted respectively to second actuation devices 60 mounted on respective vertical rods 271 of the backrest 27. By such arrangement, the support frame 45 is pivotable relative to the backrest 27 between extended and collapsed positions. In case it is needed to support the car seat 1 (see also FIG. 8), the support frame 45 is pivoted relative to the backrest 27 to the extended position whereat it is inclined to the backrest 27 and has its upper horizontal rod 454 provides a support position for the front retaining portions 12 of the car seat 1. Meanwhile, each of the rear retaining portion 13 of the car seat 1 is supported by respective upper portion of the rear armrest 38. In this manner, the car seat 1 is securely supported. Referring to FIG. 9, in case the car seat 1 is not needed, the support frame 45 is pivoted relative to the backrest 27 to a collapsed position whereat the support frame 45 is pivoted towards and urged against the backrest 27 so as to provide a space for the stroller seat 4′.
